Abstract: 1,264,838. Testing profiles electrically. RANK ORGANISATION Ltd. April 10, 1970 [April 16, 1969], No.19487/69. Heading G1N. In apparatus for determining the deviations of the contour of a closed curve from its basic shape, the contour is sensed by a feeler gauge associated with an electrical transducer and from the resulting signals the D. C. component and fundamental A.C. component are separated out and fed to a recorder together with the total signal, to produce an indication of the actual profile against a reference contour. As shown, Fig,2, the profile of a test piece 1 rotated by a motor 4 is sensed by a stylus 6 and the resulting electric profile signals fed to chart recorder 12 also driven by motor 4. Analysis of the signals is controlled by switching unit 24 driven at half speed by motor 4. During the first complete revolution of the test piece 1, corresponding to 180 degrees of unit 24, switch S2 is closed, relay RLA is energized and the profile signals are fed through closed contacts RLA-1 to an integrator 16, which measures and stores the mean D.C. component, and through closed contacts RLA-2 to a differential harmonic analyser 17 which selects and stores the fundamental A.C. component. During the second revolution of the test piece switch S2 is opened and switch S3 closed, selectively energizing relays RLB and RLC, controlling contacts RLB-1, RLC-1, as determined by a selector switch SA. With switch SA in position b, contact RLB-1 is open and RLC-1 closed, whereby the stored D.C. and fundamental signals from 16, 17 are jointly fed to chart 12 to produce a reference profile curve for the test piece. With switch SA in position α, contacts RLB-1, RLC-1 change over and the stored signals are substrated at 21 from the profile signals, to feed to chart 12 an eccentricity-corrected profile signal.

Abstract: 1289091 Seaming MAE RHIANDO 8 Oct 1969 [8 July 1968] 32401/68 Heading B5K [Also in Division F2] In the manufacture of a plastics reinforced pipe from a sheet of reinforced thermoplastics, the edges of the sheet are shaped to facilitate seam welding after it has been helically wound on to a former. This shaping may be performed by heating the sheet and shaping its edges around the sides of a metal strip positioned just above the sheet. Additional metal strips at the sides of the sheet ensure that a uniform cross-section is formed. This results in the sheet having a U-shaped crosssection. Surplus plastics at the top of the-sheet's U-shape is bent over on to the top of the metal strip by wheels placed above the strip. The sheet may be formed into other crosssections than the one described. Welding may be by means of ultra-sonics or gas or hot air or simple heat sealing using heated needles on a wheel. In operation the edges of the joint soften with the heat and fuse under the influence of a slight pressure so as to seal the spiral joint'as it rotates on the former.

Abstract: 1329092 Coated sheet materials DUNLOP HOLDINGS Ltd 3 Nov 1970 [16 Dec 1969] 61143/69 Heading B2E Sheet material having a pattern which may extend into or completely through the thickness of the sheet is produced by forming a porous sheet from fragments of a resinous material by treating a layer of the fragments with a liquid to cause partial coalescence of the fragments, removing excess liquid if necessary, applying to the porous surface so formed a pattern and heating the patterned sheet and/or pressing it into a coherent, non-porous state. The pattern may be printed on to the porous surface and the printing medium allowed to penetrate into the layer. The liquid may be a solvent which renders tacky the surfaces of the fragments, excess solvent being removed by, e.g. applying a vacuum, or it may be an adhesive, e.g. polyvinyl acetate and acrylic emulsions and water soluble urea-formaldehyde resins. The liquid may be incorporated in the composition from which the fragments are formed, e.g. the fragments may be in the form of powder with which is mixed porous granules such as perlite which have been impregnated with the liquid or, alternatively, with micro-capsules of a resinous or glass material encapsulating the liquid. The fragments may be formed from a thermoplastic composition such as polyvinyl chloride, vinyl chloridevinyl acetate copolymer, vinyl chloride-propylene copolymer or vinyl cloride - vinyl ether copolymer composition. In an Example, a vinyl chloride - vinyl acetate copolymer powder was mixed with porous perlite granules impregnated with acetone and the mixture spread on a porous backing paper. A vacuum was applied to the underside of the paper to draw the acetone through the layer and to evaporate any excess. A pattern was then applied to the surface of the resulting porous sheet using a water-based ink, the vacuum being maintained during printing. The printed sheet was then pressed.

Abstract: 1334362 Detecting radioactivity; neutron camera UNITED KINGDOM ATOMIC ENERGY AUTHORITY 25 Nov 1971 [7 Dec 1970] 58117/70 Headings H4D and H4F The outputs of a neutron camera 1, Fig. 1, e.g. that described in Specification 1,225,058, defining the X and Y co-ordinates of a neutron source, can occur at random and the display on a cathode ray tube of the spatial distribution of the sources change so frequently as to be rendered unusable. The use of a store 10 is thus proposed storing 512 sets of co-ordinates, such that at any instant, sets n to (n + 511) are stored, the 512th set replacing the nth set when it occurs and the 513th set replacing the (n + 1)th set when it occurs and so on. This results in there always being 512 sets co-ordinates for providing a substantially steady display for the CRT. The detection of a new neutron source video pulse by pulse shape discriminator 2 causes the readout/display of the store contents to be interrupted whilst the new co-ordinate set is stored.
